When the tech was new I was really hopeful for something that could act as an interactive research and literature library. Conceptually a machine that generates responses based on an overview of a field of science or history that it's specialized for could have been pretty useful to people.
But no, I can't make sex talk with that or use it to generate porn images of people I know so guess we'd better hook it up to social media and make it run on engagement. Nothing is economically useful unless it's fleecing the mentally ill

Is Ratatouille a prequel to Evangelion?
